This dataset contains oceanographic data collected along the continental slope submarine canyons, en route to and returning from the North Atlantic Seamount Chain. ROV operations were conducted on the seamounts both inside and outside the U.S. EEZ. Operations focused on areas of high potential for discovery and of interest to the management community. ROV dives were conducted mostly during the day, while CTD casts and acoustic mapping occurred when the ROV was on deck. Data acquisition from shipboard sensors includes navigation data, meteorological data (wind, air temperature, relative humidity, barometric pressure), and oceanographic data (thermosalinograph, remote temperature probe, sound velocity probe, bathythermograph).

Following annual ship shakedown and patch tests, EX1301 completed the comprehensive mapping of the Northeast canyons and the adjacent continental shelf carried out by the cruises involved in the Atlantic Canyons Undersea Mapping Expeditions (ACUMEN) 2012 project.

Transit mapping operations will collect bathymetry, sub-bottom profiles, water column backscatter, and seafloor backscatter over the continental shelf and Claypile Bank in accordance with request from the scientific community. Survey mapping operations will collect continuous bathymetry, sub-bottom profiles, water column backscatter, and seafloor backscatter over the area to the south of Flower Garden Banks NMS, also in accordance with the scientific community. Data will provide details about biological habitats in the area and improve understanding of the ecological connection between mid-water and deepwater biological communities. During EX-14-02 Leg 2, multibeam, single beam, and sub-bottom profile data will be collected 24 hours a day and XBT casts will be conducted at an interval defined by prevailing oceanographic conditions, but not to exceed 6 hours.

ROV exploration of the Northeast U.S. Deepwater Canyons complementing and continuing the work of the 2012 ACUMEN expedition. The two legs of EX1304 will perform systematic exploration, investigating deep water areas in and along the northeast canyons off the U.S. East Coast.
